My advice is to be very, very, very wary when doing so. Feeling passionately about something will not necessarily make good art, because it is not, in itself, art.
You can not sit down, open a vein, and put your pen in your blood to write. You have to bleed into the inkwell, add the extra ingredients, and alchemically transform your blood into ink before it is ready to write with.
This is because you must be able to view your dream dispassionately. See if it works. If any part does not fit the story, it must be ruthlessly expunged, no matter how passionately you adore it. You must be able to recognize the difference between cheap shots and an integral part of the work, and the more passionately you feel the resentment you are working off, the harder it will be. You must be fair to the bad guys, based on people or holding views you naturally detest, and justify to the readers the good guys, whom you think intrinsically sympathetic because they support the views you find intrinsically appealing.
You must turn your passion into art before it will be any good at all.
